我需要将JSON从客户端POST到服务器。我正在使用Python 2.7.1和simplejson。客户端正在使用请求。服务器是CherryPy。我可以从服务器获取硬编码的JSON(代码未显示),但是当我尝试将JSON发送到服务器时,我得到“400 Bad Request”。
这是我的客户端代码:
data = {'sender': 'Alice',
'receiver': 'Bob',
'message': 'We did it!'}
data_json = simplejson.dumps(data)
payload = {'json_payload': data_json}
r = requests.post("http://localhost:8080", data=payload)
这是服务器代码。
class Root(object):
def __init__(self, content):
self.content = content
print self.content # this works
exposed = True
def GET(self):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(self.content)
def POST(self):
self.content = simplejson.loads(cherrypy.request.body.read())
有任何想法吗?
从请求版本2.4.2及更高版本开始,您可以在调用中使用'json'参数,这样可以更简单。
>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> r.json()
{'args': {},
'data': '{"key": "value"}',
'files': {},
'form': {},
'headers': {'Accept': '*/*',
'Accept-Encoding': 'gzip, deflate',
'Connection': 'close',
'Content-Length': '16',
'Content-Type': 'application/json',
'Host': 'httpbin.org',
'User-Agent': 'python-requests/2.4.3 CPython/3.4.0',
'X-Request-Id': 'xx-xx-xx'},
'json': {'key': 'value'},
'origin': 'x.x.x.x',
'url': 'http://httpbin.org/post'}
编辑:此功能已添加到官方文档中。你可以在这里查看:Requests documentation
事实证明我错过了标题信息。以下作品:
url = "http://localhost:8080"
data = {'sender': 'Alice', 'receiver': 'Bob', 'message': 'We did it!'}
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
r = requests.post(url, data=json.dumps(data), headers=headers)
根据请求2.4.2(https://pypi.python.org/pypi/requests),支持“json”参数。无需指定“Content-Type”。所以较短的版本:
requests.post('http://httpbin.org/post', json={'test': 'cheers'})
更好的方法是:
url = "http://xxx.xxxx.xx"
datas = {"cardno":"6248889874650987","systemIdentify":"s08","sourceChannel": 12}
headers = {'Content-type': 'application/json'}
rsp = requests.post(url, json=datas, headers=headers)
与python 3.5+完美配合
客户:
import requests
data = {'sender': 'Alice',
'receiver': 'Bob',
'message': 'We did it!'}
r = requests.post("http://localhost:8080", json={'json_payload': data})
服务器:
class Root(object):
def __init__(self, content):
self.content = content
print self.content # this works
exposed = True
def GET(self):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(self.content)
@cherrypy.tools.json_in()
@cherrypy.tools.json_out()
def POST(self):
self.content = cherrypy.request.json
return {'status': 'success', 'message': 'updated'}
这适用于Python版本3.5,如果URL包含查询字符串/参数值,
请求URL = https://baaaah2.com/ws/rest/v1/concept/
参数值= 21f6bb43-98a1-419d-8f0c-8133669e40ca
import requests
r = requests.post('https://baaaah2.com/ws/rest/v1/concept/21f6bb43-98a1-419d-8f0c-8133669e40ca',auth=('username', 'password'),verify=False, json={"name": "Value"})
headers = {'Content-type': 'application/json'}
print(r.status_code)
